Prop-wash, thanks for reply, any kind words will help him. As for the flight sim, that is about the only advice he took from me. He bought the G2 months before his plane, which was both good and bad. He became so confident flying the P52 on the sim, that he went and made that his first plane. I have to add he is good at building, the plane was a work of art. I wish he would of snapped a pic before destroying it! Anyway flight sims are good, as long as you don't get over confident.
